Radiolab Folgen

In this episode, we break the thermometer and watch the mercury spill out as we discover that temperature is far stranger than it seems. We first ran this episode in 2021: Five stories that run the gamut from snakes to stars. We start out underwater, with a species of snake that has evolved a devious trick for keeping warm. Then we hear the tale of a young man whose seemingly simple method of warming up might be the very thing making him cold. And Senior Correspondent Molly Webster blows the lid off the idea that 98.6 degrees Fahrenheit is a sound marker of health. In this episode, we break the thermometer and watch the mercury spill out as we discover that temperature is far stranger than it seems.

One spring evening in 2024, a science journalist named Rachel Gross bombed at karaoke. The culprit was a bleed in a fist-sized clump of neurons tucked down in the back of her brain called the cerebellum. A couple weeks later, her doctors took a bit of it out, assuring her it was just helping her with motor coordination — she might be a bit clumsy for a while, but she’d still be herself. But afterwards, she didn't feel like herself. So she dove into the dusty basement of the brain (and brain science) to figure out why. What Rachel found was a burgeoning new frontier in neuroscience. We learn what singing Shakira on stage has to do with reaching for a cup of coffee — and how the surprising relationship between the two is making us rethink what we think about thinking.Special thanks to Warzone Karaoke at Branded Saloon, Dr. Joanne Loewy and the Singing Together, Measure by Measure choir at the Louis Armstrong Center for Music and Medicine  (http://musicandmedicine.org/) at Mount Sinai Union Square, Dag Spicer and the Computer History Museum, Désirée Lie, Mark Gross, Daniel A.

Most of us spend some part of our lives feeling bad about ourselves and wanting to feel better. But this preoccupation is a surprisingly new one in the history of the world, and can largely be traced back to one man: a rumpled, convertible-driving California state representative named John Vasconcellos who helped spark a movement that took over schools, board rooms, and social-service offices across America in the 1990s. This week, we look at the rise and fall of the self-esteem movement and ask: is it possible to raise your self-esteem? And is trying to do so even a good idea?Special thanks to big thank you to the University of California, Santa Barbara Library for use of audio material from their Humanistic Psychology Archives and to their staff for helping located so many audio recordings. EPISODE CREDITS:Reported by - Heather Radke and Matt Kielty Produced by - Matt KietlyOriginal music and sound design by - Jeremy S.
